An entry in Fortnightly Topic Challenge #45: Flags
"Hey Pat, I got your latest tour brochure. It looks really fun; you know I love military history! But times are tough, and I did ask you for something from the budget list."
"That's what I sent...this is one of the cheapest tours I have."
"I'm trying not to get mad here Pat, but this itinerary visits four different cities across the globe. I can barely afford St. Petersburg, Florida, let alone Russia. And I'm sure it's a nice town and all, but Bremerhaven has never been in my top 10 destinations."
"Only one city, I promise! But...you've got to figure out which one it is!"
So I suspect that this is just a tour of Philadelphia, which is right about at my price point, but I can't figure out why the brochure is so complicated. Well, OK, Pat is why it's so complicated. But Philadelphia would be too easy. Can you help me figure out where this tour is going to take me? The brochure that Pat sent over is below.

The museum ships on the brochure are not individually significant, but there aren't necessarily many other choices out there which convey the same information.
